CROSS-REFERENCE TO RELATED APPLICATIONS

The present application is a continuation of U.S. Provisional Application No. 15/178,195, filed Jun. 9, 2016, which claims priority to U.S. Provisional Application No. 62/173,213 filed Jun. 9, 2015, the entire contents and disclosures of each of which are hereby incorporated by reference in their entireties.

FIELD OF THE INVENTION

The field of the invention relates systems, methods and devices for quickly and easily securing movable objects using one or more concentric counter coil tie-downs.

BACKGROUND OF THE INVENTION

Various items and objects may move when transported, jostled or otherwise disturbed if not properly secured. Solutions have been created to tie cargo down securely and also to secure boats to fixed shore locations when docking including “O” rings, “D” rings, cleats and other traditional prior art tie downs. Bungee cords, tied ropes, buckles, ratchet straps and other means of securing items and objects have been used in the past. However, these means are often difficult to manipulate and can be easily loosened, even when used properly. Where buckles have been used, they frequently rub against cargo and may cause scratches, deformities and other damage. Thus, needs exist for simple, efficient and effective tie downs.

SUMMARY

Properly securing cargo, items and objects can be a lengthy process and may require significant human and mechanical strength in order to ensure the cargo, items and objects will not move during the course of transportation or fixing to a particular location. Military and non-military uses of securing means for items and objects can be beneficial in various contexts and industries such as: the transportation industry, marine contexts, storage industries, the oil industry, the construction industry, the medical industry, the mining or other heavy industrial industries, the aerospace and other space travel industries, home industries, recreational industries, the agriculture industry, the firearms industry, light and heavy commercial industries and various others. Particular examples of usage in some of these industries and contexts are as follows:

Transportation industry uses can including use with: semi-trucks, trailers, moving trucks, pickup trucks, automobiles, vans, cargo on ships, submarines or other vessels. Varied uses can include roof racks for vehicles and in-vehicle installations such as inside trunks, truck beds, semi-truck bodies, ship hulls or decks,

Marine context uses can include use with: diving, mooring or otherwise securing boats, ships, submarines, tugboats, sailboats, speedboats, fishing boats or other vessels.

Storage industry usage in various contexts can include storage of cargo located on docks, container loading docks, piers, parking lots, trade show floors or other locations.

Home industry usage can include: pet tie downs, home storage use, plant hangers, landscaping or others.

Recreational industry usage in camping or other leisure time activities and can also include use in various sports such as mountain climbing, spelunking, canoeing, kayaking, hunting, birdwatching and others.

Agricultural industry usage can include: farming, livestock, ranching and others, and many other uses are contemplated. Many of these applications already have individual prior art means of securing items including various infrastructure.

Light and heavy commercial industry usage can include securing advertising balloons on a car lot, bicycle securing locations and various others.

Systems, methods and devices as described herein can be installed in locations adapted for various previous existing infrastructure with minimal or no modification. This makes the concepts and functions described herein ideal for use in a variety of environments and fields. They can also provide simplistic ways to secure items that requires minimal time and effort and that are highly effective, especially as compared with the deficiencies present in the prior art. Further, youths or small individuals can be as effective in securing items and objects as strong adult males based on application of the principles and teachings described herein and shown by way of example with respect to the various embodiments.

DETAILED DESCRIPTION

Before the present subject matter is described in detail, it should be understood that this disclosure is not limited to the particular embodiments described, as such may vary. It should also be understood that the terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting, since the scope of the present disclosure will be limited only by the appended claims.

FIG. 1 shows an example embodiment of a concentric counter coil tie-down assembly 100 from a perspective view. As shown in the example embodiment, concentric counter coil tie-down assembly 100 can include a mounting assembly area 101 and a concentric coil upper area 105.

A first coil 108 of concentric coil upper area 105 can be an interior coil and can be a right-handed helical coil that is coupled to a coil-side surface 103 of a base plate 102 of mounting assembly area 101 and that has a post 106 at its central axis. A second coil 110 of concentric coil upper area 105 can be an exterior coil and can be a left-handed helical coil that is coupled to coil-side surface 103 of base plate 102 and that has post 106 at its central axis. Second coil 110 can have a second radius from its central axis that is greater than that of the first radius of the first coil 108 to the central axis when viewed from a top down perspective, as shown and described with respect to FIG. 5.

Mounting assembly area 101 can include a base plate 102 that can be substantially planar, convex or concave in various embodiments. Base plate 102 can be rectangular, triangular, circular, oval or various other regular and irregular shapes and can be made of one or more varied materials such as metals, carbon fiber, plastics and others. Base plate 102 can include a raised cylindrical lower housing 104 with a central axis oriented perpendicular to base plate 102 at or near its center with a hollow interior. Raised cylindrical lower housing 104 can be removably or permanently coupled to first, coil-side surface 103 of base plate 102 such that it is monolithic or includes multiple components in various embodiments. Raised cylindrical lower housing 104 can have a third radius from its central axis that is greater than that of second radius of second coil 110.

Base plate 102 can also be permanently or removably coupled with post 106, located at the co-located central axes of lower housing 104, first coil 108 and second coil 110 and be oriented perpendicular to base plate 102. Post 106 can have a threaded screw-type lower section (not shown) that can be installed or otherwise coupled with an appropriately sized complementary hole (not shown) in base plate 102 that has complementary threading receiving grooves. In some embodiments the hole in base plate 102 and lower section of post 106 may not be threaded and post 106 can simply pass through the hole such that it extends through base plate 102.

Mounting assembly area 101 can include a first separator 112 that separates a second, mounting-side surface (not shown) of base plate 102, located opposite coil-side surface 103, from a mounting location that concentric coil upper area 105 is to be mounted to. First separator 112 can be substantially planar and have opposing first and second surfaces that serve to protect the mounting location from damage that could be caused by friction with mounting-side surface of base plate 102, including: scratching, denting, scraping and other damage.

In the example embodiment, concentric counter coil tie-down assembly 100 can be mounted to a substantially flat mounting location, such as a substantially planar piece of metal. As shown in the example embodiment, a second separator 114 can be substantially planar and have opposing first and second surfaces that serve protect an opposing surface of the mounting location from similar damage which could be caused due to friction with a clamp 116, such as a butterfly nut, of mounting assembly area 101 that is located adjacent the second surface of second separator 114. In the example embodiment, first and second separators 112, 114 are rubber and have holes for post 106 to pass through. In other embodiments they can be other materials or combinations of materials such as: foams, plastics and others. In some embodiments, clamp 116 can include receiving means such as a threaded hole for receiving a complementary threaded screwing end of post 106 for coupling.

FIG. 2 shows an example embodiment of a close-up of a concentric counter coil tie-down assembly 200 including a coupling 202 of a second coil 110 to base plate 102 from a perspective view. In the example embodiment, one or both of first coil 108 and second coil 110 can be welded or otherwise permanently coupled to base plate 102 in an assembly manufacturing step. Typically, a manufacturer can weld first coil 108 to the first, coil-side surface 103 of base plate 102 in a desired position, location and orientation before welding second coil 110 to the first, coil-side surface 103 of base plate 102 a desired position, location and orientation. A portion of a first helical loop of first coil 108 and of second coil 110 can be flush with the first, coil-side surface 103 of base plate 102 surface such that a stable weld is created and forces against coils 108, 110 during use are distributed more evenly with respect to base plate 102 than if a single coil cross section is welded against the first, coil-side surface 103 of base plate 102.

Each of first coil 108 and second coil 110 can have a different cross section in the example embodiment. The cross section of first coil 108 can be smaller than the cross section of second coil 110. In other embodiments these dimensions can be switched or reversed. Alternatively, each coil can have equal cross sections. While the example embodiment shows circular cross sections for first coil 108 and second coil 110, in some embodiments cross sections can be oval, triangular, square, rectangular, pentagonal or other regular or irregular polygons. Additionally, coils can have ridges or other additional secondary structures that are not depicted in the FIGs. For instance, one or both coils 108, 110 can have a helical ridge around its exterior, perpendicular bars passing through and coupled to one or both coils 108, 110 to allow for additional knotting of ropes, nubs, hooks or others. Various other secondary structures are contemplated.

FIG. 3 shows an example embodiment of a concentric counter coil tie-down assembly 300 with an elongate tie-down element 302 from a perspective view. As described elsewhere herein, in an example embodiment, one or more concentric counter coil tie-down assembly 300 can be installed or otherwise coupled to a mounting location to provide a tie-down securing location for various items and objects. As an example, with respect to FIGS. 7 and 12A-12E, concentric counter coil tie-down assembly 300 could be installed on the upper surface of one or more side-walls of the bed of a pickup truck and cargo in the bed of the pickup truck could be secured such that it will not move during transportation. As shown in the example embodiment of FIG. 3, a rope, cord, twine, strap, steel cable, chain or other such tie-down structure 302 which is attached or coupled to, placed or oriented over or around, or is otherwise associated with one or more cargo items or objects can be swiftly and easily wrapped once, twice or other numbers of times between gaps oriented circumferentially with respect to a first and second coils of concentric coil upper area 105 to secure the cargo to the mounting location. Removal of the rope, cord or other structure 302 can also be swiftly and easily accomplished by unwrapping from the concentric coil tie-down assembly 300.

Also shown in FIG. 3 is a cylindrical upper housing 304. Cylindrical upper housing 304 can have a centrally located hole 308 that post 106 can slidably or otherwise couple with. As shown, post 106 can include a head 310 that prevents cylindrical upper housing 304 from sliding free or otherwise decoupling from post 106. Cylindrical upper housing 304 can cover coils 108, 110 and can have the same radius and be coaxially located with raised cylindrical lower housing 104. One or more drainage holes 306 can allow water or other substances to pass through cylindrical upper housing 304. Similarly, in some embodiments drainage holes can allow water through cylindrical lower housing 104, base plate 102 or both.

FIG. 4 shows an example embodiment of a concentric counter coil tie-down assembly 400 from a side view. In various embodiments, first and second coils 108, 110 of concentric coil upper area 105 can have particular degrees of offset from each other and can have identical or different helical pitches, creating different orientations with different characteristics. These can create horizontal “V” shapes with differential angles 402 at various locations with respect cross sections of the coils 108, 110. These “V” sections can serve to secure ropes, cords or other structures by pinching the structures between loops of coils 108, 110. In the example embodiment, first and second coils 108, 110 of concentric coil upper area 105 can have a ninety degree offset from each other with a substantially identical helical pitch. In the example embodiment, the ninety degree offset creates about a twelve-degree differential angle 402 having a zero degree offset, creating a substantially horizontal “V” shape between cross sections of coils 108, 110.

FIG. 5 shows an example embodiment of a concentric counter coil tie-down diagram 500 from a top-down view. As shown in the example embodiment, post 106, first coil 108 and second coil 110 have are coaxially oriented. Various materials and combinations of materials can be used for each of these components, including: steel, plastic, polymers, carbon-fiber and other currently existing and future developed materials. While the example embodiment shows that both first coil 108 and second coil 110 are circular, one or both can also be different shapes when viewed from a top down perspective in different embodiments, such as: ovals, triangles, squares, rectangles, pentagons, stars, diamonds, or various other regular or irregular polygons or shapes. Central post 106 may or may not be included or required in some embodiments. Additionally, one or more posts can be included that are located exterior to second coil 110 in various embodiments. Also shown in the example embodiment, is a first coil radius 502 from a central axis and a second coil radius 504 from the central axis. In the example embodiment, first coil radius can be approximately 14 mm while second coil radius can be 504 can be approximately 20.5 mm with a gap 506 between coils of about 1 mm. In other embodiments, many different dimensions can be used.

FIG. 6A shows an example embodiment of a counter coil tie-down assembly diagram 600 having an inner coil 108 and an outer coil 110. In the example embodiment, horizontal gaps 606 a-c between inner coil 108 and outer coil 110 can be about 12 degrees wide.

FIG. 6B shows an example embodiment of a use case for a concentric counter coil tie-down assembly diagram 600 from a side view. As shown in the example embodiment, concentric counter coil tie-down 600 can be mounted in a securing location using mounting assembly area 101 components. Then, a rope 602, which can be a 5 mm nylon rope in some embodiments, can be wrapped at least once between outer coil 110 and inner coil 108 by pulling one or both ends of the rope across a plane substantially perpendicular to a central axis of coils 110, 108. This can initially begin the securing of the rope 602 with respect to the concentric counter coil tie-down 600, before a user can then loop one or both ends of rope 602 around the concentric counter coil tie-down 600 a desired number of additional times to further secure the rope 602. Since the beginning movement is the initial securing of rope 602, additional loops can help to reinforce rope 602 and prevent slipping, withdrawal or other movement with respect to concentric counter coil tie-down 600 in order to secure it. In many embodiments, outer coil 110 and inner coil 108 can each have circular cross sections with no flat surfaces. Exterior surfaces (circumferential with respect to cross sections of the components) of outer coil 110 and inner coil 108 can be treated to increase their coefficient of static friction and reduce the chance of a rope accidentally loosening. Also, as shown in the example embodiment, upper and lower housings as shown with respect to FIG. 4 are not always required.

FIG. 6C shows an example embodiment of a counter coil tie-down assembly diagram 600. In the example embodiment, inner coil 108 and outer coil 110 are coupled to a mounting plate that is circular (not shown). The mounting plate, first and second separators 112, 114 and third spacer 604 are shown as uncoupled from each other in the example embodiment but are slidably coupled with bolt 106, which is coupled to clamp 116, a butterfly nut. Inner and outer coils 108, 110 have a height of about 25 mm in the example embodiment, while outer coil 110 has a diameter of about 41 mm. Mounting plate (not shown) can have about a 41 mm diameter and a 4 mm thickness and can be cylindrical in the example embodiment. First separator 112 can be about 90 mm by 57 mm by 3 mm, second separator 114 can be about 90 mm by 57 mm by 2 mm, third separator 604 can be about 51 mm by 65 mm by 15 mm and clamp 116 can be about 6 mm×80 mm. Mounting plate (not shown) can be chrome, first separator 112 can be chrome plated steel, second separator 114 can be a non-slip rubber protector and third separator 604 can be a rubber spacer that can snugly fit within a complementary sized hole in a pickup truck bed. Bolt 106 can be about 6 mm by 80 mm.

FIG. 7 shows an example embodiment of a truck bed installation diagram 700 with a plurality of concentric counter coil tie-down assembly units 706 a-f installed from a top-down view. In the example embodiment, the plurality of concentric counter coil tie-downs 706 a-f can be installed at locations along the top sidewalls of truck bed 702. In other embodiments, various other installation locations can be used, such as on the floor surface of truck bed 702, raised from the side of truck bed 702, along a side wall of truck bed 702, along truck bed 702 walls, on an upper exterior surface of a wheel well, on a tailgate, or various other locations. Truck bed 702 can be loaded as is commonly performed for transporting boxes, sculptures, suitcases or other cargo, objects and items. A user can then quickly secure the cargo by wrapping rope 704 around at least one of the various concentric counter coil tie-downs 706 a-f in the manner described above with respect to FIGS. 6A-C, where unsecured ends of rope 704 can be looped around the concentric coils and extend over, around and through cargo as appropriate. This can cause rope 704 to create a “web,” similar to that seen in FIG. 7, preventing cargo from moving or flying out of truck bed 702.

FIG. 8 shows an example embodiment of a concentric counter coil tie-down assembly diagram 800 featuring a plurality of mounting elements which does not include a center post from a side perspective view. As shown, in various embodiments of the current apparatuses and systems, center posts may not be required to secure ropes. In the example embodiment a concentric counter coil upper section 802 can be coupled to a first mounting plate 806 with a plurality of pass-through holes, such as the two shown. The two pass-through holes can receive securing bolts 808 a, 808 b which can pass through complementary holes in a first protector 810 that can be non-slip rubber, a mounting location (not shown), a second protector 812 that can be non-slip rubber and a bottom plate 814 before being secured with optional locking washers 816 a, 816 b and locking nuts 818 a, 818 b. Bolts, locking nuts and locking washers can be triple chrome plated steel in some embodiments.

In the example embodiment, dimensions of each of first mounting plate 806, first protector 810, second protector 812 and bottom plate 814 can be about 75 mm by 50 mm by 4 mm. Dimensions of holes in each of these component can be sufficient to accommodate coupling with securing bolts 808 a, 808 b with dimensions of 6 mm by 60 mm and can be chrome. Locking nuts 818 a, 818 b can be triple chrome plated steel with nylon threads.

FIG. 9 shows an example embodiment of a vehicular roof-rack installation diagram 900 including a plurality of concentric counter coil tie-down assembly units 902 a-f and various mounting parts from a top-down perspective view. In the example embodiment, similar to the description with regard to FIG. 7, a plurality of concentric counter coil assembly units such as the six assembly units 902 a-f can be steel, triple chrome plated mounted to a vehicle roof rack 904 in order to assist in securing cargo. Boxes, suitcases, mattresses, and other cargo can be placed in an appropriate transporting location and rope 906 can be looped around concentric counter coil assembly units 902 a-f in order to prevent or otherwise inhibit movement of the cargo during transportation. In the example embodiment shown, concentric counter-coil assembly mounts 902 a-f can be dual mounts as shown and described with respect to FIG. 8.

FIG. 10 shows an example embodiment diagram of a concentric counter coil tie-down unit 1000 and a plurality of concentric counter coil tie-down protective caps 1002 a-b from a side perspective view. As shown in the example embodiment, protective caps 1002 a-b can be cylindrical caps with an open end, a closed end and an inner diameter slightly larger than a maximum diameter of an exterior coil or an upper and lower housing of a concentric counter coil, such as concentric counter coil 1000. As such, they can snugly fit over, cover and protect the concentric counter coils from weather, unintentional contact or other damage. Protective caps 1002 a-b can be made of any appropriate material including chrome steel, other metals, plastics, polymers, rubbers, treated wood or others. Additionally, protective caps 1002 a-b can have an interior lining of rubber or other softer protective lining permanently or removably coupled to its exterior material, which can be metal, to further protect concentric counter coils and maintain a tight seal. In some embodiments, this can be a 1 mm rubber lining. Protective caps 1002 a-b can have customizable outer surfaces which allow for display and changing of emblems, decals or other identifiers by users or sellers. In an example embodiment, protective caps can have dimensions of about 41 mm tall and 26 mm diameter with a 1 mm thick inner rubber lining.

FIG. 11 shows an example embodiment diagram of a protective bag 1100 containing a plurality of concentric counter coil tie-down protective caps 1102 a-d from a cutaway side view. In an example embodiment protective storage bag 1100 for protective caps 1102 a-d can be provided for storage and safekeeping of protective caps 1102 a-d when not installed on concentric coils. In some embodiments, protective storage bag 1100 can have two or more individual compartments. Protective storage bag 1100 can be made one or more of canvas, cloth, wool, polyester, or any other appropriate fabric or combination of fabrics. Also, as shown, a drawstring 1104 can be used to seal the bag for carrying. Any number of other additional accessories can be included or coupled with respect to appropriate locations of protective storage bag 1100, such as: handles, straps, viewing ports, body or shape maintaining elements such as flat or rounded surfaces, tool compartments and others, as are known in the art. Protective bag 1100 can be sized differently in various embodiments but in the example embodiment it can be about 120 mm by 100 mm by 100 mm and can be canvas for storing protective caps 1102 a-d having dimensions of about 41.5 mm by 26 mm by 1 mm with 1 mm inner rubber lining. This size allows for storage in a glove box or other small compartment in a vehicle.

FIGS. 12A-12E show example embodiments of a concentric counter coil tie-down assembly 1202 installed on a pickup truck 1200 from varying distance perspective views. In the example embodiments, the concentric counter coil tie-down installation 1202 is installed on an upper surface of a side-rail of a pickup truck bed. As shown, upper coil area 1206 includes a first, inner helical coil 1210 and a second, outer helical coil 1212 oriented opposite each other. In the example embodiment upper ends of first coil 1210 and second coil 1212 are permanently coupled by a welding 1211. Upper coil area 1206 components are permanently coupled to lower mounting area 1208, as shown by weld 1216 between second coil 1212 and mounting plate 1214. Also shown is a cord 1204 that can be looped in a horizontal fashion through installation 1202 in order to secure items with respect to installation 1202.

FIG. 13A shows an example embodiment of a concentric counter coil tie-down assembly 1300 with a plurality of mounting elements from an oblique side-perspective view. In the example embodiment, assembly 1300 includes an upper section 1302 and a lower section 1304. As shown in the example embodiment, upper section can include a cap 1310, an inner coil 1306 and an outer coil 1308. Inner and outer coils 1306, 1308 can be coupled with cap 1310.

As also shown in the example embodiment, inner and outer coils 1306, 1308 can be coupled with lower section 1304, as described with respect to FIG. 13E. Lower section 1304 can include a mounting plate 1312 and one or a plurality of mounting screws 1314 a, 1314 b that pass through threaded or unthreaded holes in a mounting plate 1312 and a seal 1318. Mounting plate 1312 and seal 1318 can be permanently or removably coupled in various embodiments.

Mounting screws 1314 a, 1314 b can be thumbscrews, having upper gripping elements, such as ridges, that can quickly and easily be adjusted by hand by a user without the need for any tools in the example embodiment. However, in some embodiments, mounting screws 1314 a, 1314 b can be different types of screws that require screwdrivers, wrenches or other tools. Mounting screws 1314 a, 1314 b are threaded such that they can be coupled with mounting nuts 1316 a, 1316 b respectively. As shown, mounting nuts 1316 a, 1316 b include arms such that they can be gripped by a user's fingers and not require additional tools to hold while adjusting.

In the embodiment shown, two posts 1322 a and 1322 b can be used to prevent the arms of mounting nuts 1316 a, 1316 b from rotating a full 360 degrees around mounting screws 1314 a, 1314 b when rotatably coupling in embodiments where they have complementary proportions. As such, posts 1322 a, 1322 b can stop mounting nuts 1316 a, 1316 b in a desired position to allow mounting nuts 1316 a, 1316 b and mounting screws 1314 a, 1314 b to tighten and secure concentric counter-coil installation 1300 with respect to an installation location, such as on a surface of a truck bed as a user rotates mounting screws 1314 a, 1314 b by hand, with a screwdriver, hex connector, wrench or other implement or tool. As the user rotates mounting screws 1314 a, 1314 b, mounting nuts 1316 a, 1316 b rotate into the desired position and contacts posts 1322 a, 1322 b, which act as a stopping element. Then, as a user tightens them with respect to each other, mounting nuts 1316 a, 1316 b can move upward with respect to seal 1318; seal 1318 can move downward with respect to mounting nuts 1316 a, 1316 b; or both can occur. Seal 1318 can be a rubber protector mount below mounting plate 1312 and can be complementary sized with a rectangular or other shaped opening of a truck bed wall or surface, such that it snugly fits within the opening. In various embodiments, these openings in the truck bed surface can be standard sized across trucks of a manufacturer product line, across the industry or custom created.

This can be repeated by wrapping around and between coils 1306, 1308 of assembly 1300 as many times as desired or appropriate for a particular embodiment.

FIGS. 15A-15F show an example embodiment of a concentric counter coil tie-down assembly 1500 with a cylindrical mounting component 1522 from various views.

FIG. 15A shows an example embodiment of a concentric counter coil tie-down assembly 1500 with a cylindrical mounting component 1522 from a front perspective view. In the example embodiment, assembly 1500 includes an upper section 1502 and a lower section 1504. As shown in the example embodiment, upper section includes a cap 1510 with a gripping ridge 1512 coupled to an inner coil 1506 and an outer coil 1508. Gripping ridge 1512 of cap 1510 can allow a user to move and adjust upper section 1502 with respect to lower section 1504.

As also shown in the example embodiment, inner and outer coils 1506 and 1508 respectively can be coupled with an inner cylinder 1528 that can be slidably inserted within a top area 1514 of cylindrical component 1522. A permanent coupling area 1516 can allow cylindrical component 1522 to fit within a complementary sized hole in mounting plate 1518 of lower section 1504.

Mounting plate 1518 can include one or a plurality of mounting screw holes 1520 a, 1520 b to allow for mounting with a desired mounting location. Cylindrical mounting component 1522 can be a hollow outer mounting cylinder that includes one or more tracks 1526 through the wall of cylindrical mounting component 1522 and can function as height positioning grooves. These tracks 1526 can allow a user to adjust a height of an inner cylinder 1528 with respect to cylindrical mounting component 1522.

Inner cylinder 1528 can be complementary sized to slidably fit within a hollow interior of cylindrical mounting component 1522. This can allow inner cylinder 1528 to be slidably adjusted along an inner axis within cylindrical mounting component 1522 using one or more set pins 1524, which can be permanently coupled with inner cylinder 1528 and extend radially outward from an exterior surface of inner cylinder 1528.

FIGS. 17A-17F show an example embodiment diagram of a concentric counter coil tie-down assembly 1700 from various views. With respect to the example embodiment, a manufacturing process will now be described. First, a base 1702 can be welded to first inner spring 1704 and outer spring 1706. Next a steel chrome plate 1708 can be coupled with base 1702. A non-slip rubber protector 1710 can be coupled to or otherwise arranged adjacent to plate 1708 before a rubber spacer 1712 is arranged on the opposite side of rubber protector 1710. Bolt 1714 can be slidably coupled through each of these components through complementary sized holes in their centers before being secured by a butterfly nut 1716 or other securing mechanism.

In some contemplated embodiments, a miniature version of the counter-coil apparatuses described herein can be used in a shoe and lace system in order to secure the lace with respect to the shoe. In some of these embodiments, the miniature version can include concentric counter-coils with a single helical turn each, while in other embodiments, include concentric counter-coils with multiple helical turns each. This can be mounted or otherwise secured to shoes in convenient locations to replace the need for tying the shoelaces together while still securing them in location.

Systems, apparatuses and methods as described herein can be created in a variety of different sizes, which can be embodiment specific and dependent on a maximum load weight of objects or items a user desires to secure in the particular embodiment. For instance, an apparatus or system intended for mooring a ship would be much larger and require much greater sturdiness than one to prevent items from moving in a pickup-truck bed.

Related to this concept, coil size, height, cross sectional profile (e.g. diameter in circular embodiments) can be customized to provide securing for different cord or rope cross section sizes. In general, the gap between loops of the coils can be a limiting factor in determining the maximum rope size that can be effectively secured in a particular embodiment.

Also related to these concepts, various component materials used to implement the embodiments described herein can be embodiment specific. These materials can include, but are not limited to: molded high strength plastics, powder coated steel, stainless steel, aluminum, iron, brass, carbon fiber, metal composites, plastic composites and various combinations thereof.

Manufacture of various embodiments can likewise be accomplished in embodiment specific fashion.

In various embodiments, manufacturing methods can be practiced in a modular fashion, such as creating an upper unit section and a lower unit section. In some embodiments, the upper unit section can be manufactured by first coupling an inner coil to an upper mounting plate and then coupling an outer coil to the upper mounting plate. Next, a cap, such as an upper housing, can be coupled to an end of the inner coil, outer coil or both, opposite the upper mounting plate. Lower units can similarly be manufactured by mounting lower unit components to a lower mounting plate, which in some embodiments is the same as the upper mounting plate.

In some embodiments, a first end cap, such as an upper housing, can be coupled to a first end of the inner and outer coils. Similarly, a second end cap, such as a lower housing, can be coupled to a second, opposite end of the one or more coils. In these embodiments, second end cap can then be coupled with a mounting plate.

In some embodiments, one or more coils can be directly coupled to a mounting location. As such, no separate mounting plate or lower housing may be necessary or even desired. Those in the art would understand that various manufacturing steps can be changed in order or omitted based on the unique circumstances, conditions or orientations of creating particular assemblies. Likewise, mounting base plates can be customized to allow for multiple uses or individual specialty uses (e.g. a truck mounting versus a trailer mount).

The publications discussed herein are provided solely for their disclosure prior to the filing date of the present application. Nothing herein is to be construed as an admission that the present disclosure is not entitled to antedate such publication by virtue of prior disclosure. Further, the dates of publication provided may be different from the actual publication dates which may need to be independently confirmed.

It should be noted that all features, elements, components, functions, and steps described with respect to any embodiment provided herein are intended to be freely combinable and substitutable with those from any other embodiment. If a certain feature, element, component, function, or step is described with respect to only one embodiment, then it should be understood that that feature, element, component, function, or step can be used with every other embodiment described herein unless explicitly stated otherwise. This paragraph therefore serves as antecedent basis and written support for the introduction of claims, at any time, that combine features, elements, components, functions, and steps from different embodiments, or that substitute features, elements, components, functions, and steps from one embodiment with those of another, even if the following description does not explicitly state, in a particular instance, that such combinations or substitutions are possible. It is explicitly acknowledged that express recitation of every possible combination and substitution is overly burdensome, especially given that the permissibility of each and every such combination and substitution will be readily recognized by those of ordinary skill in the art.

In many instances entities are described herein as being coupled to other entities. It should be understood that the terms “coupled” and “connected” (or any of their forms) are used interchangeably herein and, in both cases, are generic to the direct coupling of two entities (without any non-negligible (e.g., parasitic) intervening entities) and the indirect coupling of two entities (with one or more non-negligible intervening entities). Where entities are shown as being directly coupled together, or described as coupled together without description of any intervening entity, it should be understood that those entities can be indirectly coupled together as well unless the context clearly dictates otherwise.

While the embodiments are susceptible to various modifications and alternative forms, specific examples thereof have been shown in the drawings and are herein described in detail. It should be understood, however, that these embodiments are not to be limited to the particular form disclosed, but to the contrary, these embodiments are to cover all modifications, equivalents, and alternatives falling within the spirit of the disclosure. Furthermore, any features, functions, steps, or elements of the embodiments may be recited in or added to the claims, as well as negative limitations that define the inventive scope of the claims by features, functions, steps, or elements that are not within that scope.
